9 Claims.

This invention relates to cinches or devices for adjustably clamping orholding the ends of belts, straps, bands or the like and it isespecially, though by no means exclusively, adapted for use in clampingthe ends of web or other heavy belts, such as safety beltsused by windowwashers, and in the description terminology appropriate to Windowwashers belts and cinches therefor, will be used for convenience.

Objects of the invention are to provide a device of the characterdescribed which shall (a) provide practical insurance against breakageeither of the cinch or the belt by providing not only great strength inthe cinch itself but also. and especially by so shaping and sizing thebeltcontacting portions of the cinch as to minimize the tendency of thefastening means to Wear or injure the surface of the belt and tomaterially lessen the diierence in the tension on the opposite surfacesof the belt; (b) be of extreme simplicity and economy in manufacture,structure and use and (c) insure against slippage of the belt inrelation to the cinch under conditions of intermittent as well ascontinuous tension on the belt.

With these and other objects in View, all of which shall more fullyhereinafter appear, the invention comprises certain novel constructions,combinations and arrangements of parts as shall now be described andclaimed and as illustrated l in the accompanying dra-wings in which Fig.l is a view of the cinch with the ends of a belt secured thereto, beingin front elevation as positioned in use upon the wearer of the belt.

Fig. 2 is a view of the assembly shown in Fig. 1 looking in thedirection of the arrow 2 at the bottom of Fig. 1.

Fig. r3 is a sectional view on line 3--3 of Fig. l.

Fig. 4 is a view in the same position as Fig. l but showing the twoelements of the cinch nested without the belt.

Fig. 5 is a View of Fig. 4 looking in direction of the arrow 5 at Fig.4.

Fig. 6 is a view like Fig. 5 but showing the two elements of the cinchexploded or separated.

Fig. 7 is a sectional View on line I-'I of Fig. 4, and

Fig. 8 is a fragmentary sectional view on line 8-8 of Fig. `4.

rThis cinch, embodying the present invention, is composed of twoelements which are duplicates in construction except that one of theelements has outwardA extensions with upstanding lugs shown at theextreme right in all of the figures,

side elevation, at Figs. 2, 5 and 6. The two elements, wheninterrelatively endwise reversed, will nest as illustrated at Figs. 4, 5and 7.

The element having the lugs is designated as part A and the element nothaving the lugs will be designated as part B.

Each of the parts A and B has side bars I0, interrelatively spaced atleast the width of belt ll, and end bars I2 and I3 for engaging the beltII.

The outside portion, approximately half or more of the thickness, of theside bars I0, is of a generally elongated rectangular shape and is l to7, but most clearly at Figs. l and 4, and, in 5:5

indicated at Ilia, which portions Ia are the same throughout except thatsaid portions Illa on part A have reduced extensions Illb whichterminate in upstanding lugs Ic adapted to slidingly enclose ns Icl ofpart B, which fins are extensions of the inner half or less (inthickness) or bars I 0. Lugs Ic are also adapted to engage the ends Illeof portions Ia of bars I0 of part B, when the belt is clamped in thecinch, and limit interrelative longitudinal movement of parts A and B inone direction, as clearly illustrated yat Figs. l and 2. The enclosureof fins Ind of part B, between the extensions IUD and lugs I 0c of partA, prevents lateral interrelative movement of parts A and B.

Cross bars I2 are substantially triangular in cross section, the base ofthe triangle, which is the outer surface I 2a of the bar I2, beingcurved, giving a curved outer surface to bar I2.

The belt-contacting surfaces of cross bars I3 are preferablyeccentrically or French curved throughout, all as indicated at I3a andas clearly illustrated at Figs. 3, 4 and 7 and as, and for the purpose,hereinfter more fully described.

The portion lila, may have the reduced extension I 0b on part B as wellas on part A, as illustrated at Figs. 2, 5 and 6, but, in part B, theseextensions Iilb do not carry the lugs IIJc.

Each portion Illa has a portion If project-A ing toward the reducedVextension Illb on the opposed part and adapted to slidily engage theupper surface or edge of said reduced extension Illb on the opposedpart, whenever the belt II is not between the bars I2 and I3, asillustrated at Fig. 5 and at the right at Fig. 2.

Each end of a band or belt attached to the cinch may be threaded betweenthe bars I2 and I3 and gripped therebetween by opposite pulls upon thetwo portions of the belt or band, but, in general practice, when in usefor a belt, it is preferable to attach one end of the belt to the cinchina more or less fixed or permanent mane
